Seems like Kusakabe-kun and Momiji are the only ones that have more than a single digit I.Q. including the uncle. Kusakabe-kun rescued the situation in a stellar manner, especially deftly manipulating the moron of an uncle. As expected, Idiot-girl did not tell her "boyfriend" what had happened and who knows how long it would have taken her, if ever, to tell him if Kusakabe-kun had not outsmarted them all. As usual, she was more concerned about the feelings of yet another 3rd wheel than she was about the feelings of her "boyfriend." Nonetheless, this does not mean that the Jerkoff 3rd wheel will no longer cause trouble.
